When winching your boat onto a trailer, a common ratio for determining your winch load capacity is 2 to 1. For example, a 7000lb boat would require a 3500lb winch. There are other factors, however, that will determine the appropriate winch size for your purposes.
The ratio can be stretched to 3 to 1 in instances when the trailer in use has high-quality rollers and is most commonly used on ramps where boats float most of the way onto the trailer.
In contrast, using a boat trailer that has wooden bunks, lacks self-alignment capabilities, and is most commonly used on ramps where the boat must be winched most of the way onto the trailer reduces the ratio to 1 to 1.
The winch I recommend is the Superwinch S5000 Trailer Winch, part # SWS104176. This winch will work for your 7,000-lb boat if your are using them in a situation where the trailer has rollers or the boat would float most of the way on the trailer.
If you are deciding between the two winches the largest winch will always be the best choice. The larger winch will not have to work as hard as the lower capacity winch and this will improve performance and help extend the life of the motor.
